So basically no self-learning will change things, which is as we suspected, but at the time did not have access to these labels ...

Kim, I'm going to post this over on Ross-Tech, and continue the DTC related discussion there rather than cross post, but any further Pico related stuff or New Updates on actual progress, will be back to let this forum know

Ok, we're nearly there, and in fact from a test perspective, and Pico usage for this car today ..., we are ...

New Egear ECU arrived, as did a donor LP560, with good Egear ECU.The Donor ECU allowed us to confirm the car works on a good ECU without generating faults, and does drive, that's the good news!

Kim, Just FYI - The block 64 values on the Donor Car were 0 + 1 + 0 + 0 the same as our old ecu.

We figured out how to reset the Steering ECU error And Got the new ESP coded, so now the car is potentially error free!

BUT ...

The new Gerbox ECU, refuses to learn at least 2 elements:1. Clutch Characteristic Self tuning (Routine 3) (adaptation to degree of deterioration)2. Clutch Kiss Point Self tuning (Routine 1) - must be ubdertaken with engine running at >70c temp+ any other coding that we're not aware of, possibly the first element to allow these 2 routines to operate! ... and both of which are needed.

The other critical configuration for a new ECU is the Grid Self tuning (Routine 2), which is successful & generated 14 + 1.... but the The block 64 values on the New ECU remain 0 + 1 + 255 + 255 - so 2 elements noted above shown in "negative" condition (well we knew that, but anyway)!So, anyone have any ideas on what/how to fix this?

Can't say what was corrupt in the Old ECU, but at least we know that once the new ECU is initalised/learnt the fix is complete!

I wonder if there is an Eeprom in there that can be lifted and moved over to the new unit and bingo. Kerrching

As already discussed if the "fault" is in the Eeprom data (Corruption) then all we do is shift the problem to the new TCU. I agreed with you at the time. Still stand by that.

Eeprom data corruption is not going to affect Can Voltages or cause noise on the network. Is it ??Missing Messages, Invalid data, gremlins and the Like - Yes agreed.

The process is easily reversible should it not work. Then we also have the opportunity to clone the TCU from the Donor vehicle you hopefully still have. It is not corrupted and we have proof of that. We may have to convert some Hex to ASCI and/or Decimal to realign the VIN so it is all matched, happy and legal.

All said and done, it is MED 9, regardless of which car it is bolted into, a Gallardo or a Golf with DSG??

Just a suggestion, Plan B or C should you be struggling.

Of course if you can get it coded as per VM preferred methods then I would encourage you to take that route. It is a no brainer.

Would be shame to let the dealer take away the Eureka moment, the Glory, the lap of honour after all your efforts and heartache.
